Composite resins, or tooth-colored fillings, provide good durability and resistance to fracture in small- to mid-size fillings that need to withstand moderate pressure from the constant stress of chewing. They can be used on either front or back teeth. They are a good choice for people who prefer that their fillings look more natural. Composites cost more than amalgam and occasionally are not covered by some insurance plans. Also, no dental filling lasts forever. Some studies show that composite fillings
Operative Dentistry & Whitening
We don’t usually do silver fillings anymore, because they contain a small amount of mercury. The mercury is bound to the silver in a compound that is very stable and only very small amounts of the mercury are detectable. Never-the-less, silver fillings are unattractive, although they do last a long time and are very durable. In some cases where high strength is needed, or if the filling is in an area, below the gum that we can’t keep dry, your
Dental Teeth Whitening There are only to chemical compounds that can whiten teeth: Hydrogen Peroxide and Carbamide Peroxide Hydrogen Peroxide is stronger but contact with the gums should be avoided as it can bleach and even burn them if a protective coating is not put over them before using the product. Carbamide Peroxide is a more gradual type of whitening and can be used in the dental trays and bleaching strips. With this bleaching agent, contact with the gingiva is
Inlay and Onlay Sometimes a filling may not be strong enough to adequately restore a tooth. In this case, the dentist may elect to do an inlay. This is a white piece of porcelain or other reinforced material, that is either milled by a computer or made by a lab, that goes down into the space that the filling would have gone. When an inlay covers the tooth crown cusps, it is called an onlay.
Pin and Post Tooth Build-Up When a tooth is badly broken down from an accident or dental decay, it is sometimes necessary to place a pin in the tooth and build up the tooth with a restorative material, like composite resin or amalgam or core build up material. When a root canal is done a post anchor can be placed down into the root providing even more support. Usually a crown is later placed on top of the tooth to
